HGT1N40N60A4D

Overview

The HGT1N40N60A4D is a 600V N-channel Insulated Gate Bipolar Transistor (IGBT) with an integrated anti-parallel hyperfast diode, manufactured by Fairchild Semiconductor. It operates in the SOT-227B package and supports continuous collector currents of 110 A at 25°C case temperature. The device features a typical saturation voltage of 1.7 V at 40 A and 15 V gate drive. Switching characteristics include a fall time of 55 ns at 125°C junction temperature and turn-on energy loss up to 850 µJ. Total power dissipation reaches 298 W at 25°C, with a thermal resistance from junction to case of 0.42 °C/W for the IGBT.

Feature Summary

• Optimized for high-frequency switch mode power supply applications

Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels. Confirm datasheet revision status as the product may be obsolete. Ensure handling procedures account for electrostatic discharge sensitivity inherent to insulated gate devices. Validate package integrity against SOT-227B specifications before integration into circuit designs.

Selection Notes

Evaluate thermal management requirements based on the 0.42 °C/W junction-to-case resistance. Consider gate drive voltage limits not exceeding ±20 V continuous. Assess switching losses against operating frequency constraints defined by turn-off delay and rise times. Verify short-circuit withstand capability matches system fault protection thresholds.

Part Context

This component belongs to the SMPS Series IGBT family designed specifically for high-frequency power electronics. Originally designated as Developmental Type TA49349, it was produced by Fairchild Semiconductor before corporate acquisitions. The device utilizes OptoPlanar technology for improved switching performance compared to earlier generations.

Replacement Considerations

Check for direct equivalents within the same voltage and current ratings. Verify pinout compatibility with the SOT-227B isolated tab configuration. Ensure reverse recovery characteristics of the integrated diode meet application snubber requirements if replacing with non-integrated solutions.
